Hillary Clinton cannot become US President: Carly

In an unhinged personal attack, Republican presidential candidate Carly Fiorina dug up the extra-marital trysts of Hillary Cinton's husband and said the Democratic frontrunner cannot become the US president as she continues to lie to the American people.

"Hillary Clinton will do anything to gain and hang on to power, anything," corporate leader-turned politician Fiorina said during the GOP undercard presidential debate in Iowa. "Listen, if my husband did what Bill Clinton did, I would have left him long ago," the 61-year-old said.

Clinton, 68, is eyeing to become the first woman president of the US and is likely to win Democratic Party nomination. A former First Lady, Clinton served as the Secretary of State in the first term of the Barack Obama administration.

Fiorina, a former Hewlett-Packard CEO who is struggling to gain traction before voters head to the caucuses, unleashed a series of crowd-pleasing insults at Clinton and said Clinton continues to lie to the American people.
